Motion sensors

Motion sensors are devices that detect movement within a specified area. They work by using various technologies, such as infrared, ultrasonic, or microwave signals, to sense changes in the environment. When an object or person moves within the sensor's range, it triggers a response, such as turning on lights, sounding an alarm, or sending a notification. Commonly found in security systems and automatic lighting, motion sensors enhance safety and convenience by enabling systems to react to movement without manual input. Their applications span homes, offices, and public spaces, contributing to energy efficiency and security.
